Developing a framework for safety verification and control synthesis using semi-algebraic sets.
摘要
The paper explores safety verification and control synthesis using semi-algebraic sets. It focuses on verifying positive invariance of controlled systems, proposing algorithms for constructing Control Barrier Functions (CBFs), and synthesizing controlled invariant sets. The approach leverages real algebraic geometry theorems to formulate sum-of-squares constraints for safety validation. Special cases like single polynomial super-level sets and High-Order CBFs are discussed, along with techniques for verifying inclusion in a given safe region. The complexity of the problem is analyzed, showing it to be NP-hard.
